Hypotaenidia obscuriora Hume, Str. Feath., ii, p. 302 (1874) (Andamans). Hypotaenidia obscurior. Blanf. & Oates, iv, p. 162.
Vernacular names. None recorded.
Description. Similar to the preceding bird but darker and larger. The upper plumage is much blacker, the breast a deeper grey and the chin and throat much less white.
Colours of soft parts. Iris dark brown; bill Indian red, tips of both mandibles and whole culmen deep horny-brown; legs and feet dark greenish-horny (Davison).
Measurements. Wing 129 to 136 mm.; culmen 33 to 36 mm. The female is duller and rather greyer.
Distribution. The Andamans and Nicobars.
Nidification. The nidification differs in no way from that of the Indian bird and Osmaston took a wonderful series of their eggs from the first week in June to the end of August. The full clutch seems to be four to six eggs and these are on an average much more richly coloured than those of H. s. gularis. One hundred eggs average 36.0 x 27.5 mm.: maxima 39.2 x 28.7 and 37.0 x 29.4 mm,; minima 32.7 x 25.2 and 32.7 x 25.0 mm.
Habits. Similar to those of the preceding bird. It is extremely common in the Andamans and in some of the Nicobar islands, haunting swampy places both inside and on the fringe of forests.
